AC Infinity SUNCORE S3, Waterproof Seedling Mat with Heat Controller 10" x 20.75", UL & MET Certified Heating Pad, for Indoor Gardening, Hydroponics, Germination, Cloning

Everything AC Infinity makes is very dependable and designed to work. This heat mat is thermostatically controlled and heats consistently.

I used this very basic heat mat to warm some transplants to stimulate root growth and it works well.You plug it in, under the little greenhouse dome you may be using and the gentle heat from the mat does the rest. It's basic and it works well with no complaints .Did not monitor temperature, so I took it at face value, nothing was over-heated or damaged, so it's fine.Just needed to provide steady heat to my cuttings and did not go the whole "scientific" route of monitoring, just plug and play.Very basic, works fine IMO and I'd buy one again, and recommend for simple, basic needs.

I was surprised by how good the quality of this mat is. The adjustable temperature really works, I tested the temperatures before trying the seeds on it. Low is barely warm, high is a little too warm even for my chilly basement, and I found that about 1/3 past medium turned out perfect. Almost all of my bell pepper seeds came up.I just ordered another of these so I can start the rest of my seeds at once. I am completely new at starting plants from seeds but this makes it easy. I highly recommend this mat!

Was the right size, seems well put together and looks nice. Doesn't get too hot after 10 hours on high and seems to be running well.

I wish I got this sooner. It makes germination much easier. No more looking for a warm spot to put the seeds while they germinate in a towel. This is water resistant and very durable. The controller is very simple and easy to use. I never need to go above medium heat. If you are working with clones, this is also a must have. It makes propagation a breeze. It adds just enough warmth to create the right amount of moisture in the enclosure.

start on low and use a thermometer! bought for seed starting in peat pellets. first day, made the mistake of using the high setting on the mat plus the grow light, after a few hours I measured the peat at 100 degrees which is too hot. room was only 65 degrees. i turned the mat down to lowest setting that night, in the morning the peat was about 70-80 which is a good temp. with the light on again and the mat at low setting, after a few hours it was up to 90 degrees which is still a bit too hot. so now I am using the mat only when the light is off and at low setting. definitely glad I got this mat with the temperature control.

Great little heating mat. It can give off heat from 70° to about 90° on high. The best is dispersed all around without any dead zones. It has a temp controller that you need to more of less guesstimate how much heat you think you'll need.It comes with a storage case. And to my amusement, it comes with a "How to grow hemp" full color and image like 40 page booklet. Who needs Google when you get a free guide 😂Love AC infinity products. They know what they're doing.

I recently purchased the AC Infinity SUNCORE S3 Waterproof Seedling Mat with Heat Controller for my indoor gardening needs. While the heating pad itself functions well and is UL & MET certified, there are a couple of areas where I feel it could be improved.Firstly, it would be more convenient if the SUNCORE S3 readily connected to the 69PRO control system. As someone who already owns the 69PRO, it would have been great to have seamless integration between the two devices. It would have made temperature control and monitoring much easier, eliminating the need for multiple controllers.Additionally, the absence of a built-in temperature gauge is a slight drawback. Having an integrated temperature gauge would provide real-time monitoring of the heat levels, allowing for better precision and control over the germination and cloning processes.That being said, the SUNCORE S3 does function as described and provides consistent heat for my seedlings. The waterproof feature is a plus, as it adds an extra layer of protection and peace of mind. The 10" x 20.75" size is suitable for small to medium-sized gardening setups.In summary, while the AC Infinity SUNCORE S3 Waterproof Seedling Mat with Heat Controller is a reliable product, I believe it could be enhanced by offering seamless connectivity to the 69PRO control system and incorporating a built-in temperature gauge. These improvements would elevate the user experience and provide more comprehensive control over the heating process.
